Recently I tried to talk Bobby the hubby into getting a home air filtration system as he's a smoker. But those dang air filtration systems are ugly. And big. And did I mention they're ugly? Yuck. So the next best thing is to get plants & these 10 plants are rated the best in filtering the nasties out of the air we breathe by removing 90% of formaldehyde, benzene and trichloroethylene within 24 hours. 24 hours!
